The injury-enforced withdrawal of tournament drawcard Nick Kyrgios has thrown the Kooyong Classic into disarray.
Once the go-to Australian Open warm-up tournament boasting the likes of Roger Federer and Andre Agassi among past champions, the loss of Kyrgios has left the event with a bunch of virtual no-names.
Frenchman Gilles Simon at world No.15 and Belgian David Goffin at 16 are the highest ranked players in the field, which was expanded to 12 this year.
But the loss of Kyrgios, whose face is painted on every inch of promotional material, means the tournament is without a "name".
The polarising Kyrgios withdrew midway through the second set of his match against Goffin on Wednesday after winning the first set in a tie-break.

"The purpose of this tournament is to prepare players for next week's Open.
"To make them play if they're injured is contrary to that."
Cooney said there was no question Kyrgios' injury was genuine and applauded his attempt to play on into the second set before having to bow out.
